Thermal energy harvesting

Thus, in the first case - that of paper recycling - in evaluating the impacts, we must also take account of the production ofXMJ of electricity in the local conditions for conventional electricity production. In the second case - that of thermal energy harvesting - we also need to consider the conventional production of 7 kg of paper from wood, when evaluating the impacts. We can then perform a vahd comparison of two systems which have the same products 7 kg of paper andXMJ of electricity.

In the case of enhanced geothermal systems (EGS), thermal energy is obtained by pumping water onto hot rocks in the ground rather than harvesting hot water already there. 

The facilities used to harvest the ocean thermal energy are called OTEC plants (Ocean Thermal Energy Conversion). To achieve their maximum potential they must be located in the open ocean near the equator, far from any market. Several schemes to transmit their output to the market have been examined. The most practical appears to be use the electric power to electrolyze water to produce hydrogen and oxygen. The oxygen can be vented and the hydrogen liquefied for shipment to market. This scheme allows the OTEC plant to produce a storable fuel that can be used for most energy needs.

On the other hand, single-wall CNTs (SWCNTs) can efficiently absorb and convert photon energy into thermal energy and have excellent thermal conductivities. Thus, they can act as a nanoscale heat source and thermal conduction pathway to heat the crosslinked LCP matrix effectively [51]. Furthermore, the resultant crosslinked PLCP/SWCNT nanocomposites exhibited effective photoactuation not only by white light but by near-IR irradiation as well [52]. Such nanocomposites were used to direct sun-driven artificial heliotropism for solar energy harvesting [53]. 

Batteries and energy harvesting Fabric-based batteries and fabrics that use the kinetic energy or the thermal energy of the wearer or their environment to generate electric power. 

The proof of concept that SC-SOFCs can be considered for portable power generation was provided by Shao etal. [19], who successfully powered a 1.5 V MP3 player with a miniature two-ceU SC-SOFC stack. The heat generated from the exothermic reactions allowed rapid start-up from cold start to stable power in less than 1 min and thermally self-sustained the system. However, the low cell efliciency of current SC-SOFCs questions their practical implementation, and energy-harvesting appHcations where energy is generated from waste gases and efficiency plays a secondary role seem more adequate.
